Following the steps in this section should help in pinpointing the cause and avoiding wasting money by replacing the wrong parts. Drive a car for 10 minutes and check the engine temperature again, it should be close to 180-220°F or 82-105°C. The sensor should read close to ambient temperature at this time. If you pinch your hose make sure that you are aware of the belted accessories and the fan. Only a few times have I needed to employe some actual help from a shop to get something done. I believe the reason it all came back is the superstat opens gradually and early. Meaning the valves sensor is detecting a high voltage input.
Close it when you get fluid. If either fault is recorded again on the next engine startup, code P0128 is triggered. P0128 Symptoms Symptoms of coolant temperatures being too low will first be the check engine light. Any help would be greatly appreciated. The intent of the P0128 Jeep code is to indicate a faulty thermostat.
What causes the P0128 code? If other codes are present, they must be addressed first. Additionally, once the 160º F threshold is achieved, the recorded engine temperature must not fall below 160º F during operation. Remote start is disabled when there's an active trouble code. That's my next step, I think. Check to make sure the seal did not stay attached to the engine block. The first thing to do is to clean the valve.
If you have any doubt as to repairs on your vehicle, please contact your technician. Mine just fell out, but you may need to rock yours just a little to break the seal. At temperatures lower than this the control strategy must be modified to ensure stable combustion, generally at the expense of and hydrocarbon emissions. Remove the thermostat from the housing. Figured it was cheap enough to replace both while the coolant was drained. Ensure idling occurs in a well ventilated area. Code p0128 - coolant temperature thermostat, The obdii trouble code p0128 - coolant temperature below thermostat regulating temperature means that the engine does not reach expected temperature after running for sufficient time, or in other words, takes too long to warm up.
Once the operating range is approached, the thermostat then begins to allow coolant flow through the radiator avoid overheating of the engine. Remove the thermostat housing from the engine. Twist the upper radiator hose back down and slide the end over the thermostat housing. Is this related to the temperature outside? Replacing the thermostat often solves the. If the temperature significantly exceeds this value, overheating of the engine can cause major engine damage.
This is an order and no return policy part. Separate pass and fail thresholds are used in order to improve accuracy of the diagnostic. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. Mercedes thermostat replacement - p0128 - instructions, If the thermostat fails in the open position, it prevents the coolant from reaching normal operating temperature resulting in an engine that does not warm up properly and an engine warning light illuminating. This is kind of optional.
If you remove the radiator cap, make sure that it is not hot prior to removing. If the connector is okay, then generally the sensor is at fault. It just lifts up and then pulls forward. Not 100% certain on this one On the 3. If this is the case, the connectors will typically deteriorate and cause a poor connection. This can be due to carbon build up on the valve, a bad valve, or a bad solenoid. The information contained on this site is presented for informational purposes only.
This also fixed my driverside heat for some reason. Use a flat tip screwdriver to tighten the two 2 hose clamps. They're a cinch to replace if you've had some minor car repair experience. Check the engine coolant level. This one was only 6 mo old Well replaced that Stant stat with a Stant superstat.
I haven't cleared the code or done anything, yet. The temperature from the thermometer should be around 200 degrees fahrenheit, normally. I'm not even sure were it sat before. Letting them run too cool can problems after an extended period of time. The ohm reading will change with the temperature. I think I found my culprit.
I just left mine till the morning. P0128 code courtesy of the Torque App. Sent from my iPhone using Thanks Jeepy for the informative info. As mentioned before, the engine requires the coolant to be in a certain range for the most efficient engine operation. Yep, made a little mess out of this one. Engine coolant temperature has an ideal temperature for engine operation that is normally between 90-100 degrees Celcius or 194-212 Fahrenheit.
